GRAIN-BINDER.

ELECIFICATION forming part of Letters Patent No. 477,992, dated June 28, 1892.

Application filed October 4, 1888- Reuewed May 7, 1892. Serial No 482,139- (No model.)

To all whom it may concern:

Be it known that I, PETER PAUL CoLER, a citizen of theUnited States, residing at Clyman, in the county of Dodge and State of WViscousin, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention relates to the tripping devices which set the binding mechanism in motion, to means for regulating the size of the gavels and the compression thereon, and. to means for ejecting the bound bundles from the binding-receptacle; and it consists in a pivoted outside compressing and tripping finger which forms the outer wall of the binding-receptacle, yields slightly to the pressure of the accumulated gavel, and trips the binder into action, is then looked against further outward movement until the bound bundle is to be ejected, when it is unlocked and falls below the plane of the binding-table to permit the bundle to pass over it, and is finally restored to its normal position; in forming the side of the cord-slot in the binding-table of loose leaves, the inner edges of which, or those farthest from the needle, are hinged and the outer edges, or those adjacent to the needle, held at any desired; height to regulate. the size of the binding-receptacle at the waist of the bundle; in means for raising these outer edges of the leaves during the forward movement of the needle to compress the gavel from below, and in the further combinations and details of construction whereby I am enabled to carry out these general as well as other features of minor importance of myinventiou, as will be hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a rear elevation, partly in section, on the line 1 1 of Fig. 5, of so much of a binding mechanism as is necessary to illustrate'the application of my invention thereto. Fig. 2 is a similar View ofa portion of the mechanism, the parts shown oocupyiugdifierent positions from those shown in the preceding figure. Fig. 3 is afront elevation showing the gear-train through which the binder is driven and the immediate tripping mechanism by which it is thrown into or :held out of operation. Fig. 4 is a similar view of some of the sameparts occupying different ne'ath. Fig. 11 isavertical central section through the same in the line of the cord-slot; and Fig. 12, a vertical transverse section on the line 12 12 of Fig. 10, seen in the direction indicated by arrows.

The binder-frame proper consists of the I usual front upright post A, having rearwardly-extending, overhead, and subtending arms A A which support the needle-shaft B, with its needle B and forward crank B and the .tyer-shaft C in the ordinary manner. 1 The binding table or deck D rests upon sill-bars D D which are carried upon tie-bars or brackets E F, securely fastened at their outer ends to the subtending arm of the postframe and provided with suitable feet cf, by which they are attached to the sill-bars, and with other feet 6 e f f by which they are attached to the tubular bars G G, upon which the entire binding mechanism is supported. The constantly-driven packer-shaft II is carried in suitable bearings in these tie-bars or brackets and has the usual double crank hand swinging packer-arms H, whiohare projected through slots inthe binding-table and force the grain into the binding-receptacle near its outer edge. The binding mechanism is actuated by a trip-pinion Ion the constantly-revolving packer-shaft in the usual manner,

the pinion being loosely mounted on the shaft and connected therewith at intervals by means of the spring-pressed driving-dog or trip-dog I, pivoted on the pinion and engaging lugs '11 on the ends of across-head 2", firmly,

soon red on the front end of the packer-shaft.

An intercepting pawl'or trip-latch J is pivoted on the frame-for instance, upon the adjacent outer tubular frame-bar Gand normally projects with its tre end into the path of the trip-dog to arrest itand disconnect the clutching mechanism, but when withdrawn from the path of the dog liberates it and permits it to clutch the pinion to the shaft, as will be readily understood by those skilled in the art to which my invention appertains. Such withdrawal is accomplished by the triprod J, fixed to the heel of the trip-latch andextending rearwardly along the binder-frame parallel with the subtending arm thereof and at its rear end beneath the cord-slot fixed to the trip-lever J which is pivoted to the frame in axial line with the pivot of thetrip-latch,

provided with a segmental web having a,

notched flange j at its periphery, engaged by a spring j, wound about the projecting end of the adjacent tubular frame-bar, which in this instance serves as a journal for said lever, one end of the spring being caught over a pinfifrom the pipe and the other end entering one of the notches in the flange, by means of which the tension of the spring may be regulated and the tripping pressure on the bundle adjusted at pleasure;

The tyer-shaft O is driven through a train of gear-wheels K K K from the trip-pinion, the wheels K and K being-mere idle-wheels,

while the wheel K which serves as the main.

wheel of the binder, is firmly connected to the tyer-shaft and turns it, and is further pro vided with a wrist-pin 70, connected by a pitman 70' to the crank on the front of the needle-shaft, through which the needle on the rear end of the shaft is operated in the usual manner.

The mechanism so far as I have described it is substantially similar to the well-known form of Appleby binder, which form I have chosen to illustrate the application of my tripping device, as it is the form now most extensively used and is best known in the commercial world; but it is also applicable to other forms by slight variations in detail that will adapt it to them without departing from the spirit of my invention.

The compressing and tripping finger L, which forms the outer wall'of the binding-receptacle and against which the grain is packed or compressed, is loosely pivoted on the rear end of the needle-shaft, being provided with perforated ears or lugs Z, which embrace the bar of the tripping-finger is a spring L, the expansion of which tends to keep the stopshoulder of the cam against the inner edge of the base-plate from the trip-finger, the studpins on the base-plate and cam-seat holding the spring in place.

On its lower edge the trip-cam has a straight cam-track or resisting beating-surface M',with a slight projection or hook m at its inner end and a recess or notched depression m at its outer end, from which a projecting guard or tail ll/l extends outwardly and is curved concentrically with the axis of the needle-shaft. A lateral offset M projects rearwardly from the hub or shank of the trip-cam and stands in the path of a lug m from the hub of the needle for a purpose that will be hereinafter explained. The under side of the trip-cam is borne against by the upper free end of the trip-lever, which stands in the vertical plane of the tripcam, as shown, so that the rocking of said cam shall depress the lever, thereby disengaging the trip-latch and starting the binding mechanism, as heretofore explained.

The operation of my device as thus far explained is as follows: When the parts are in their normal position, as shown in the first figure, and the-grain is being fed into the re ceptacle and against the compressor by the packer-arms, said compressor is held in its position by the spring interposed between it and the trip-cam, and the cam is borne up by the trip-lever, which'is pressed thereagainst by its adjustable spring with any desired pressure. The trip-lever normally bears against the inner end of the straighttrack of the trip-cam, and is consequently in a position to offer its greatest resistance to the movement of said cam, its resistance being greater than that of the spring between the cam and trip-finger,

. which spring will be compressed by the pressure of the grain against the finger before the trip-lever will yield; but the instant the friction between the track and trip-lever is overcome and the latter is started the expansion of the spring will accelerate the movement of the cam and instantly throw the lever vinto its tripping position, as indicated by dotted lines in Fig. 1, where it rests in the recess m of the cam. This movement of the trip-lever is communicated through the trip-shaft to the triplatch, raising it from the engagement with the trip-dog shown in Figs. 1 and 3 to the posi{ tion shown by dotted lines in Fig. 1 and by full lines in Fig. 4, where it stands out of the path of the dog, permitting thelatter to conneet the trip-pinion to the driving-shaft, and being held in its disengaged position by the continuing contact of the trip-cam with the trip lever; Such initial movement of the tripping mechanism permits'the compressing and tripping finger and cam to move to the positions indicated by dotted lines in Fig. 1, where the 'cam is positively locked against further movement in-such direction by the engage ment of the trip-lever with the notch in said cam, and the tripping-finger resists the press-' ure of the gavel with the full strength of .its-

supporting-spring until the knot in the binding material is completed and the bound sheaf ready to be ejected from the receptacle, the

positions of the parts being such .that the pressure of the cam upon the end of the triplever is directly toward the pivotal center of; the latter, so that no amount of force appliedto the cam can force the lever out of the notch.

In order to release the trip-cam and permit it and the trip-finger to swing down to the position indicated in Fig. 2, where it will be out of the path of the bound sheaf and allow thelatter to be ejected, I withdraw the end of the trip-lever fromthe notch, as follows: On the crank at the front end of the needle-shaft is pivoted a curved push-pawl N, held down to its .working position by a spring 91., coiledabout its pivot-pin and provided at its free end with an abrupt shoulder 01, an overhanging flange M, and a rounded projection or I breast 02 as shown in the drawings. Upon the heel of the trip-latch is a spur projection at, having an insetting ledge n upon which the lugs n of the push-pawl rests, as shown inFig. 4, when saidpawl is in action. In the normal quiescent position ofv the parts, as-

shown in Fig. 3, this pawl rests midway of-its length upon the top or point of the spur m and the trip-latch may be thrown u p, or opened to the position. shown byfull lines in Fig. 4

without materially effecting the pawl. When the binder is.tripped into action, the needleshaft crank is drawn up by the main gearwheel throughthe intermediatepitman to the position shownby full'lines .in Fig. 4 and. the pawl carried with it to a point where its shoulder at falls behind the spur n its lug n resting upon the ledge u as shown.- In the continued movement. of the .main.

wheel the crank is reversed and carried back to the position shown by dotted lines in said figure, pushing down the pawl, which en-.

gages the spur, and thereby raises the triplatch and through the trip-rod connecting the heel of said latch with the trip-lever withdraws said lever from the notch in the trip-cam, re-

leasing the cam and allowing it, together with the trip-finger, to fall to the position shown 3 by full lines in Fig. 2, so that the bundle may be ejected over them from the receptacle by the arms 0 on the t-yer-shaft.

The parts are shown by dotted lines in Fig.1 4 at the point where the pawl has pushed back the triplatch and lever to release the. trip-.

cam .and tripping-finger and is just about to slipoif and past the spurfrom the latch as. the downward movement of the crank. contin ues. Nowif thetrip latch and lever were left .entirely free when ,released from the push-pawl they would spring back to their. original position and the latch engage the, trip-dog before the. completion of. thefulli movement of the binderand. stop. it prematurely. To prevent this, 1. form on. the.tripcam the before-mentioned guard or. tail-piece, which interceptsethe trip-leverand holds it down until such time as the cam is returned to its normal position, which is accomplished by the lug on the hub of the needle-arm com-- ing, on the retreat of said arm, in contact with the lateral offset from the hub of the cam and forcing said cam back to its normal. position, releasing the trip-lever and trip-latch, which also fall back to their original positions, the latter into the path of the trip-dog, which is thereby arrested in its rotary movement, and

the trip-pinion disconnected from the driving-shaft. When leaving the binding-receptacle, the needle goes down to a point below its normal position, forcing the trip-earn before it, and then returning to its proper stopping-place. This return movement provides space enough betweenthe lug from the-nee dle and the lateral offset from the cam to permit the cam tomake its next initial tripping movement without coming in contact with and being arrested bythe'needle.

At one or both sides of the cord-slot in the binding-table I form the adjacent portions of the cover or decking of a leaf or leaves P with from the slot. The outer or free edges of these leaves bounding the slot maybe held at any desired elevation to graduate the size when they are tilted up the lower portions will rise relatively much higher than the upper portions, giving a considerable compression hinges p at their inner edges, or those farthest to the gavel in the receptacle, while notraising the upper ends of the leaves so far above the plane of the table. The inner edges of desired height by means of set-screws 23', passin g through the sill-bars of the binding-table,-

as shown in Figs. 1, 10,11, and'12, or through I any other convenient portion of the frame. At a suitable point onthe .needleare .ar-

ranged one or more lateral. arms, tappets, or

wipers Q, one at each side of the needle when two leaves are used, preferably being adj ustable,and for this purpose being pivoted to the-shank of the needle by a pin q and connected thereto along their-lcngthby a bolt q through aslot q ,in;said shank. -As the IIO theleaves may beadj usted to and held at-any needle rises to place the cord in the knotter.

these wipers come in contact with the-under sideof the leaves attheirdnner edgesandlift them oif their adjustable screw supporting-stops, and, thereby contracting the size of the binding-receptacle,compress the bundle from below. Bymeans'ot the-slotandclamping-bolt the. position -of the wipers on the needle may be adjusted so that they willraise I the leaf edges more or less or not raise them rower at their tops than at their bottom ends for the reason before stated, I do not regardthis as necessary in all cases, for in some instances they might be made of an even width throughout with beneficial results.
